(1) It is the obligation of the applicant to demonstrate to the board's satisfaction that the existing wells that penetrate the injection zone within the area of review are in adequate mechanical condition to prevent migration of injected fluid into any USDW. The board will require the applicant to submit a plan for corrective action, including the reworking, repairing or replugging of any such well(s) the board considers to be a possible avenue for fluid migration. Injection must not commence until satisfactory completion of the work required in the approved corrective action plan.

(2) The board may require that corrective action be taken if, after notice and hearing, it is shown that USDWs outside the area of review are threatened by an injection well or wells.
